Kenplas Forum ==> Blow Molding (Machine) ==> kiss-shaped distortion issues
<< Previous Topic Next Topic >>
All, Please help me figure this one out. We have a 2 bottle semi-auto PET blowing machine. For this new mold, we are getting a kiss-shaped distortion about 1/3 of the way down from the neck. We are also getting random tiny round and longer line shaped distortions on the bottles at randomly different places. The kiss-shaped one is at the same level on both bottles but not in the same horizontal position. It is only about 1/4 the size as the circumference of the bottle so it's not a ring all the way around. We have tried everything can't figure it out. The bottle is approximately 1.25 liter in volume and we are using 108 gram preforms. Any assistance would be greatly appreciated!
